ANDREW STRAND, OF MINNEAPOLIS, MINNESOTA.

VISE.

Application filed May 14, 1919. Serial No. 296,969.

To all whom it may concern:

Be it known that 1, ANDREW STRAND, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented a new and useful Improvement in Vises, of whichthe following is a specification. 7

My invention relates to vises, which are commonly used in various shops,and is particularly adapted for use where it is desired to quicklyremove the face plates from the main jaws o the vise so that other faceplates can replace the same for various kinds of work. In using a vise,it is often desirable to remove the face plates of the gripping jaws ofthe vise so as to more conveniently hold a piece or article between thevise jaws and use different sets of faces on the gripping jaws of thevise so as to hold the article in the vise in the most convenient andpractical manner, but it is an essential feature of my invention thatthe face plates of the gripping jaws be quickly removable and stillfirmly held when in place on the jaws of the vise.

It is also a feature of my invention to provide a vise with ,one of itsjaws pivoted in relation to the vise proper, so that different jaws canbe turned to extend at an angle to the other; jaw of the vise and ameans for holding this jaw rigidly in this angular position so that anarticle can be clamped between the aws of the vise, while their facesare at an angle to each other and the jaw which is set at an angle beingheld rigid against rotation while gripping the article between thegripping jaws of the vise. This is an important feature, as it overcomesand prevents the .movement of the pivoted jaw while holding any articlebetween the vise jaws.

The peculiar arrangement and combination of elements will be clearly setforth in the specification and claims.

In the drawing forming part of this specification:

Figure 1 is a side elevation of my vise.

Figure 2 is a plan view of the vise.

Figure 3 is a plan view of a detail of one of the jaws of the vise, aportion of which is broken away.

Figure 4 is a back view of one of the face plates of the vise.

Figure 5 is a side view of a variation of face plate used. on my v1se.

Figure 6 is a section on the line 6-6 of Figure 3.

The vise A has a stationary portion 2 and a movable portion 3, thegeneral construction of which is common in the ordinary bench vise. Thestationary portion is formed with a base portion 4, by which it isadapted to be secured in the ordinary manner to a bench, or other placewhere it is desired to rigidly hold the vise for use.

The portions 2 and 3 of the vise are formed with upwardly projectingmain jaw portions 5 and 6, respectively, to which are remov-ably ordetachably secured a pair of face or gripping plates 7. The grippingfaces 8 of the plates 7 can be made serrated or roughened, or of anysuitable shape to hold various articles in the vise, and in someinstances, it is desirable to have the faces 8 smooth and highlypolished, so as not to injure the article gripped in the vise. Each ofthe face plates 7 are formed with an elongated projection or tongueportion 9, which projects from the inner face 10, having curved ends 11which terminate a short distance from the ends of the face plate, andholding pins 12 are formed projecting from the tongue 9, which areformed with a beveled end 13 and a notch 14. The pins 12 of the plate 7are positioned near the ends of the projecting tongue 9, with thenotches 14 on the inner side of each of the pins so that when the plates7 are attached to the members 5 and 6 of the vise A, the notches 14 willbe engaged by the spring operated catches or bolts 15. The catches 15are slidably held in the passageway 16, formed in the members 5 and 6,and are resiliently held spaced. apart by the coil spring 17 The catches15 are formed with engaging beveled ends 18, which are adapted to engagein the notches 14 and which are similar in shape to the notches 14. Thebody portion of the catches 15 are cut away at 19 to receive the pins20, which hold the spring catches 15 from being forced too far apart bythe c011 spring 17 when the pins 12 of the face plates are removed fromthe openings 21 in the members 5 and 6, the catches being limited by theshoulders 22, which engage against the pins 20 and form a stop to holdthe catches 15 in place.

The pins 20 also hold. the catches from rotating in the opening 16, inthis manner always causing the beveled ends 18 to engage properly withthe notches 14 of the pins 12.

The faces 23 of the members 5 and 6, against which the backs 10 of theface plates engage, are formed with a recess 24 of a similar size andshape as the projecting tongue 9 on the face plate 7, so as to receivethe tongue or projecting portion 9 witha close fit, to hold the sameagainst heavy thrusts and strains when the face plates are in positionon the members 5 and 6 and in use. In this manner practically no strainis transmitted to the holding pins 12 and the catches 15 from the strainon the face plates when holding a member therebetween, and thus allowingthe face plates 7 to be easily removed when it is desired. The springcatches work automatically and allow the plates 7 to be snapped intoplace or to be quickly disengaged from the jaw members 5 and 6. The jawmembers 5 and 6 are cut away with a beveled surface 25 on either end,which allows a tool, such as 26, illustrated in dotted outline in Figure3. to be inserted between the end of the face plates 7 and the bevelededge of themembers and 6 to pry the face plates 7 free from the springcatch 15, when it is desired to, remove the same.

It is very desirable, in a machine shop or other places, to have a visewith removable face plates so that various forms of face plates can beused, but it is highly essential to have a construction whereby the faceplates can be easily and quickly removed. This feature is accomplishedin my invention, as the spring catches allow the face plates to bequickly and easily removed, still being held rigidly in position andunder the tension of the spring 17, when the face plates are attachedtothe main jaw members of the vise.

The face plate 7, illustrated in Figure 5, is formed with engagingpoints 27, which are cut up from the surface 8 of the plate and are forthe purpose of holding a leather, rubber or fiber block, such as 28.This con struction allows a soft gripping surface to be used fordelicate articles which are held in the vise A and by means of varioussets or pairs of different face plates 7 the ordinary vise can be usedfor practically any holding purpose, the spring catch holding meansbeing the essential feature in the use of pairs of removable faceplates.

The gripping member or jaw 5 is pivotally held to the body portion 2 ofthe vise A by means of the semicircular shank 29, having an enlargedhead 30 which is also of a semicircular shape, and the rearwardlyprojectmg portion 31 of the member 5 has a downwardly projectingcircular shaped engaging. flange 32, which engages a similar surface inthe body portion 2 of the vise and thus holds the member 5 rotatable ona comparatively large circle.

The outer surface of the flange 32 is serrated to form teeth The teeth33 are engaged by similar teeth formed in the movable head or grippingmember 34, so as to hold the member 5 against rotation, when it isdesired, and to hold the same rigidly against turning in variouspositions, with the gripping face carried by the member 5 parallel tothe gripping face carried by the member 6, or angularly to the same. 41threaded bolt 35, which is formed with an operating head 36 on one end,and having its other end swivelly connected to the member 34, isthreaded in the rear portion of the member 2 and moves the gripping heador member 34 into or out of engagement with the teeth 33 when theoperating head 36 is rotated. Holes 37 are formed in the head 36, intowhich a suitable tool can be inserted to operate the threaded bolt 35,and thereby move the member 34 in either direction. The recess 38, inthe member 2, holds the engaging head or member 34 in position in therear portion 2 of the vise A. Aprotecting plate 39 is secured by screws40 to the rear portion 31 of the jaw 5 and extends over the member 34and teeth 33 to protect the same against filings, etc.

In the use of the vise A, when a member .or article such as 41, which-isangular in shape, is engaged. between the jaws 5 and G of the vise, themember 34 is disengaged from the teeth 33 to allow the jaw 5 to rotateso that its face plate 7 engages parallel with the angular surface ofthemember 41 and before the jaws of the vise A are caused to grip themember 41 tightly,

the member 34 is operated to engage the teeth 33 to rigidly hold the jawmember 5 in an angular position, as illustrated in Figure 2, whereuponthe jaw members 5 and 6 can be drawn tightly against the article 41 tohold. it in the vise. It will be noted that in. gripping a member ofthis nature between the members 5 and 6 of a vise, especially where themember, such as 41, does not extend to the longitudinal center line,such as 42 of the vise, in a constructionwhere one of the jaws, such as5, is ro-- tatable, unless the rotatable member 5 is rigidly gripped inthe proper angularposit-ion in a relation to the member 6, by a means,such as the teeth 33 and the member 34, when the jaws 5 and 6 are drawntightly against the member 41, the member 5 would rotate on its pivotuntil the points or edges 43 of the ends of the gripping plates 7,opposite to the member 41, come together. Thus, instead of holding orgripping the. member 41 flatly against two angular sides, it would be atthe points 44 between the face plates 7, and would not be held rigid butwould have a tendency to -move pivotally in the jaw members 5 and 6. Bythe engaging means at the rear of the member 6, sucii! the teeth 33 andthe engaging head 34:, this is entirely overcome, and the rotatable aw 5is rigidly held in. any angular position in relation to the member 6 orparallel thereto. This feature is highly important in my invention.

In accordancewith the patent statutes I have described the principles ofoperation of my invention, together with the apparatns which I nowconsider to represent the best embodiment thereof, but I desire to haveit understood that the construction shown is only illustrative and thatthe invention can be carried out by other means and applied to usesother than those above set forth within the scope of the followingclaims:
